Emiliano Foresto; Fiorela Nievas; Walter Giordano; Pablo Bogino – Journal of Biological Education, 2024
The curriculum for undergraduate Agricultural Engineering does not usually include much laboratory practice. In order to address this, here we propose the design of a practical class on legume-rhizobia symbiosis, using an interdisciplinary approach that takes elements from botany, agriculture, and microbiology. The students perform an assay to…

Maria Cerrato-Alvarez; Samuel Frutos-Puerto; Eduardo Pinilla-Gil – Journal of Chemical Education, 2024
Calculating analytical uncertainties as a part of method validation is a relevant aspect of field and laboratory practices in instrumental analytical chemistry subjects, which usually require complex algorithms. This work describes the development and didactic use of an automatic and straightforward informatics tool, implemented in an Excel macro,…

Kim, Seong Un; Yang, Il Ho – Education Sciences, 2020
The purpose of this study is to develop a thinking process model that reveals cognitive bias through analyzing students' cognitive biases in processing experimental manuals. Twenty-two college students participated in the study. During the "making electromagnets" experimental activity, we collected students' concurrent verbal protocols,…

Papaconstantinou, Maria; Kilkenny, Dawn; Garside, Christopher; Ju, William; Najafi, Hedieh; Harrison, Laurie – Canadian Journal of Learning and Technology, 2020
The instructors of four biology-related courses at a Canadian university integrated Labster virtual labs in their courses as a pre-lab activity, lecture substitute, or to provide lab experience in courses with no on-site labs. The instructors used a backward design approach to align the labs with the learning objectives of their courses and to…

Schneider, Elia M.; Bärtsch, Amadeus; Stark, Wendelin J.; Grass, Robert N. – Journal of Chemical Education, 2019
A simple synthesis of fluorescent carbon quantum dots from lemon juice is described to introduce advanced high-school students and undergraduate college students to nanoparticle synthesis and quantum dots. The synthesis is based on the carbonization of lemon juice using only a hot plate stirrer. Column chromatography is used to separate different…

Sawant, Aakanksha Purushottam; Patil, Swapnaja Arvind; Vijapurkar, Jyotsna; Bagban, Needa Nasir; Gupta, Deepti Bhushan – International Journal of STEM Education, 2018
Background: We present an analysis of students' responses to application-based questions on the topic of growth and control of microorganisms, from a questionnaire administered to 348 second and third year students of an Indian university who were enrolled in its undergraduate programs in Biotechnology or Microbiology. We examined aspects of the…

Dasgupta, Annwesa P.; Anderson, Trevor R.; Pelaez, Nancy – CBE - Life Sciences Education, 2014
It is essential to teach students about experimental design, as this facilitates their deeper understanding of how most biological knowledge was generated and gives them tools to perform their own investigations. Despite the importance of this area, surprisingly little is known about what students actually learn from designing biological…

Cook, Anthony L.; Snow, Elizabeth T.; Binns, Henrica; Cook, Peta S. – Biochemistry and Molecular Biology Education, 2015
Inquiry-based learning (IBL) activities are complementary to the processes of laboratory discovery, as both are focused on producing new findings through research and inquiry. Here, we describe the results of student surveys taken pre- and postpractical to an IBL undergraduate practical on PCR. Our analysis focuses primarily student perceptions of…

Dasgupta, Annwesa P.; Anderson, Trevor R.; Pelaez, Nancy J. – CBE - Life Sciences Education, 2016
Researchers, instructors, and funding bodies in biology education are unanimous about the importance of developing students' competence in experimental design. Despite this, only limited measures are available for assessing such competence development, especially in the areas of molecular and cellular biology. Also, existing assessments do not…

Yang, Xinmiao; Hartman, Mark R.; Harrington, Kristin T.; Etson, Candice M.; Fierman, Matthew B.; Slonim, Donna K.; Walt, David R. – CBE - Life Sciences Education, 2017
With the development of new sequencing and bioinformatics technologies, concepts relating to personal genomics play an increasingly important role in our society. To promote interest and understanding of sequencing and bioinformatics in the high school classroom, we developed and implemented a laboratory-based teaching module called "The…

Effect of the Level of Inquiry of Lab Experiments on General Chemistry Students' Written Reflections
Xu, Haozhi; Talanquer, Vincente – Journal of Chemical Education, 2013
The central goal of this exploratory study was to characterize the effects of experiments involving different levels of inquiry on the nature of college students' written reflections about laboratory work. Data were collected in the form of individual lab reports written using a science writing heuristic template by a subset of the students…

Inlow, Jennifer K.; Miller, Paige; Pittman, Bethany – Biochemistry and Molecular Biology Education, 2007
We describe two bioinformatics exercises intended for use in a computer laboratory setting in an upper-level undergraduate biochemistry course. To introduce students to bioinformatics, the exercises incorporate several commonly used bioinformatics tools, including BLAST, that are freely available online. The exercises build upon the students'…
